Overview

What is Apache Flink?

Apache Flink is an open-source framework for distributed stream and batch data processing. It provides high throughput, low latency, and exactly-once fault tolerance semantics, making it suitable for real-time analytics and continuous computation tasks.

Key differentiator

Apache Flink stands out for its ability to handle both stream and batch processing within one framework, offering exactly-once semantics which are crucial for maintaining data integrity in real-time applications.
